Its an attempt from us to find the best BVR missiles in the world. Very little data is available about different missiles. We made a lot of efforts to find the data and specifications. It takes more than a month to complete this article so everyone please read the article fully & leave your valuable comment.
The criteria followed here is, incorporated technology and effectiveness in battle.

This article is about to give a brief idea about propulsion and different kinds propulsive devices. Here we just cover the very basics of different propulsion. A detailed article will publish sometime later.
What is propulsion and propulsion system?
Propulsion means to push forward or drive an object forward. A propulsion system is a machine that produces thrust to push an object forward. On airplanes, thrust is usually generated through some application of Newton's third law of action and reaction. A gas, or working fluid, is accelerated by the engine, and the reaction to this acceleration produces a force on the engine.
There are hundreds of different kinds of propulsion; here we only considering some of the Rocket propulsion, air breathing propulsion & electric propulsion.
Guidance is that aspect of a missile system which helps it to decide the direction in which the missile should move. Generally this decision has to be taken at very short intervals of time (1/50th of a second) during the flight of the missile.
For a specific mission, particular guidance technique is used. The different types of guidance are
Some missiles need more than one system of guidance. The requirement depends on the phase of guidance. The various guidance phases are the launch phase, the mid-course phase and the terminal phase.
Agni-VI is an intercontinental ballistic missile under development by the DRDO for the use of the Indian Armed Forces. Agni-VI will be a four-stage intercontinental ballistic missile. Agni-6 will carry a massive three-tonne warhead, thrice the weight of the one-tonne warhead that Agni missiles have carried so far. This will allow each Agni-6 missile to launch several nuclear warheads -Multiple Independently Targetable Re-entry Warheads (MIRVs) - with each warhead striking a different target. Each warhead - called Maneuverable Reentry Vehicle (MARV) - performs evasive maneuvers while hurtling down towards its target, confusing enemy air defence missiles that are trying to destroy them mid-air. And these maneuverable warheads will give Agni VI an extended range exact figure of which is currently classified. It will be taller than its predecessor Agni V, and is expected to be flight tested by 2017. Agni-VI missile is likely to carry up to 10 MIRV warheads and will have a strike range of 8,000 km to 12,000 km.
Guidance system of Agni 6 will include inertial navigation system with Ring laser gyroscope, optionally augmented by IRNSS. Terminal guidance with possible radar scene correlation (this is a kind of terrain contour mapping this improves the accuracy of missiles).
INFRARED COUNTER MEASUERS (IRCM)
IRCM can be classified into two categories passive (termed as IR suppression) & Active (Eg; decoys)
PASSIVE-(IR suppressors /Optimizers) – Minimizes the signature from aircraft
ACTIVE-(IR flares, IR jammers, Pyrotechnic IR Decoys (IR lamp on sacrificial structures)) –Confuses the IR seeker by IR jamming, Luring away towards fake target / sacrificial structure
Aircraft / Helicopters equipped with IR counter measures is not necessarily immune to attacks by IR guided missiles as counter counter measures (CCM)are also being currently developed
